Abstract

See full text

Communication equipment that is provided with an isolating switch, which is operated by placement of a handset, instead of a conventionally used insulating component. The isolating switch constitutes an electrical insulation between a charging, terminal of a base unit and an external electric circuit. This structure eliminates the necessity of providing an insulating component such as a transformer and the like, so as to achieve a cost reduction of the communication equipment, and also improves sound quality of the communication equipment. In addition, the isolating switch is arranged in Such a manner that a direction of tile force applied by the handset to depress the terminal of the base unit and a direction of the force applied by the handset to depress a switch level are separated from each other. The isolating switch has a construction that enables the switch lever to function with a small loading weight, and to keep a contact point of the switch depressed by an intense force. As a result, reliable operation of the switch is attained without increasing, the weight of the handset, since the is available weight of the handset can be utilized efficiently. Further, a mechanical structure for fixing the position of the handset can be eliminated, so as to simplify the overall structure of the communication equipment.
